Is it me or lldb for mac os x (replacing gdb) does not allow you to pipe a file into the stdin, to be used by the process being debugged?
reading the instructions there is no reference to it.
I've gone through and installed gnu gdb, but would like to take advantage of what I suppose is improved lldb capability?
(lldb) process launch -i <file>
Should do the trick. Note you can't say:
(lldb) run -i <file>
since run is an alias for process launch -- so all its arguments are passed to the process being launched.
There's a general "help" facility that can show you more about all the lldb commands.
(lldb) help process launch
would have shown you this option.
